Reverse seq
Hi all,
I thought I was not SUCH a nooby:)
How can I reverse a sequence/ vector?
i.e., turn
X <- 3 5 4 2 6 5 4 3 6
Into
X <- 6 3 4 5 6 2 4 5 3
I mean without looping and indexing.
There should be a very easy solution, shouldn't it?

psychometric functions
Hi,
I want to fit some psychophysical data with cumulative gaussians. There is
quite a convenient toolbox for matlab called 'psignifit' (formerly known as
'psychofit'). It allows the lower bound of the sigmoid to vary slightly from
zero, aswell as the upper bound to vary from one. with these two free
parameters, the fitted function is less sensitive to noisy data and
outliers.

orddom package for Ordinal Dominance Statistics
Dear R-users,
a new R package has been released named orddom.
This package provides ordinal estimates as alternatives to independent
or paired group mean comparisons, especially for Cliff?s delta
statistics. It provides basic parameters for various robust tests of
stochastic equality with ordinally scaled variables.
For two sets of data, ordinal comparison estimates are calculated such as

network-bridge - tg3 - no network
Hi,
i have some problems with xen-3.0.1 and the network-bridge script. After
''/etc/init.d/xend start'' or ''/etc/xen/script/network-bridge start''
everything works perfect (as well as the domU''s network) - but only for
a few seconds (~20s). After that the network seems to crash - no
outgoing or incoming connection possible.

Removing constants from a data frame
Suppose I have
x<-data.frame(v1=1:4, v2=c(2,4,NA,7), v3=rep(1,4),
v4=LETTERS[1:4],v5=rep('Z',4))
or a much larger frame, and I wish to test for and remove the constant
numeric columns.
I made:
is.constant<-function(x){identical(min(x),max(x))}
and
apply(x,2,is.constant) # Works for numerics
x[,-which(apply(x,2,is.constant))]
I'd really like to be able to

Off-Topic: LaTeX package listings
Hola!
I ask here since I learnt from this list that the LaTeX package listings
should be good
for typesetting R code. I encountered one problem:
\begin{lstlisting}
X %*% V
\end{lstlisting}
in the output the * in %*% disappears! same with %/%, etc, the /
disappears.
Any ideas?

bootstrap package
Hello R'ers
In previous versions of R (I now use 2.0.1) there was a package
"bootstrap". I wrote some programs that depended heavily on this package
but can unfortunately not find it on Cran today. Is there any way to
find an older version of "bootstrap" and use it with the new version -
2.0.1?

CDR extract call numbers on interval on unique callers

Unfortunately we have lots of callers who calls multiple times when they

Registered successfully, but after a minute or so no SIP messages anymore
ok, solved the firewall issue.
A first test call worked fine. Another one now still gets disconnected
after 32s.
But in FW there are no blocked packets anymore?!
And I don't understand why the registration to the same IP and same Port
is working, but not later transmission of further SIP packets? that
doesn't sound logical to me. What do you think?

First SIP-registering succeeds, second doesn't
Hi all,
I have a strange issue, with a some kind complicate architecture...
A router of our internet provider is in front of another bintec rs353j
router, at which my freepbx installation is located. However, NAT etc.
seems to work fine.
BUT: Something is not working...:
When registering my sip-trunk towards my provider (3 different
providers, all behave comparable), everything works at first.

as.list.matrix
I found the need of converting a matrix into a list of its columns
(for use with do.call), and was surprised there was no method
as.list.matrix, it could easily be a part of as.list default
I wrote
my.as.list.matrix <- function(mat) {
if(!is.matrix(mat))stop("Argument must be a matrix")
n <- NCOL(mat)
res <- vector(mode="list", length=n)

covariate selection?
Hello,
I am hoping someone can help me with the following multivariate issue:
I have a model consisting of about 50 covariates. I would like to
reduce this to about 5 covariate for the reduced model by combining
cofactors that are strongly correlated. Is there a package or function
that would help me with this in R? I appreciate any suggestions.
Thanks,
Ian
